Preheat your oven to 375 degrees.
Cut your cauliflower into small florets. Keep the size as uniform as possible to ensure even baking.
Season with your preferred Ranch dressing packet. (I use 1 full tablespoon and 2 teaspoons, but feel free to adjust according to your preferences!)
Top with fresh grated parmesan cheese.
Add more or less seasoning to your preference.
Line your pan for the easiest clean-up.
